COIN-CONTROLLED LOCK.

{I '0 all whom it may concern Be it known tha I, Gsonon G. F. Boswarm, a citizen of the United States, and a resident of Indianapolis, county of Marion, and State of Indiana, have invented a certain useful Coin-Controlled Lock; and I do hereby declare that the following is a full, clear. and exact description thereof, reference being bad to the accompanying drawings.

The object of this invention is to provide a coin controlled lock of improved construction and one which can be readily reversible and adapted for use on either 0 the lateral edges of either side of a door.

The invention is articularly adapted for use on booths and the like.

So far as known the jobber or dealer of any of the. coin controlled locks now on the market. must carry four-styles of the same lock, that is. right and left hand locks for use on both the inside and outside of a door. The use of this lock will obviate this dilliculty besides presenting other novel features.

The nature of the invention will' be understood from the accompanying drawings and the. following description and claims.

In the drawings, Figure 1 is a side elevation of the portion of a door with the device installed thereon. Fig. 2 is a front elevation of the same. Fig. 3 is a vertical transverse section on the line 3-3 of Fig. 2, and before the bolt has been withdrawn. I i 4 is a view similar to Fig. 3, but with the bolt withdrawn. Fig. l) is a section on the same line as for Fig. 3. but looking in the opposite direction. Fig. 6 is a front elevation of the upper part of the lock with the casing removed. Fig. 7 shows the same as Fig. 6, but with portions broken away and with the bolt withdrawn under the action of the front knob shaft. Fig. 8 shows the same as Fig. 7, but with the bolt withdrawn by the action of the rear knob shaft. Fig. 9 is a horizontal transverse section on the line 9-4) of Fig. 7. Fig. 10 is a front elevation of the upper portion of the lock with the casing removed and showing the parts associated to work upon the door of a different hand from that shown in Figs. 6, 7 and 8. Fig. 11 is a horizontal transverse section on the line 11- 11 of Fig. 10. Fig. 12 is a section similar to that of Fig. 11 but with the bolt inverted. Fig. 13 shows the method of closing the idle Specification of Letters Patent. Application filed November 18, 1911. Serial No. 660,107.

bolt hole. Fig. 14 is a detail of the front knob shaft. Fig. 15 is a perspective of the slot closing or indicator plate 1n an inverted position.

in detail there is shown in the drawings, a portion of a door 10 with a coin cont-rolled lock thereon having a casing 11, front knob 12, rear knob 13 and bolt 14, which is withdrawn by dropping a coin through a slot 15 in the upper part of the face of the casing 11 and turning the knob. The upper part of the casing 11 surrounds the lock mechanism, while the lower portion serves as a coin receptacle to which access may be had through a door 16 in the casing 11 and which is locked by means of a small key lock 17. There is a rear late 18 secured to the door to which the casing 11 is secured by means of screws 19 and upon which plate the various parts of the lock mechanism are mounted. There is a plate 20 extending transversely of the rear plate 18 and extending outwardly therefrom upon which the bolt 14 rests. The belt 14 1S substantially H-shaped in cross section, as shown in Figs. 3 and 4, and at one end 21 the legs are substantially longer than for the rest of the bolt, see Figs. 9 and 11. There is an Italian-cross shaped slot through the bolt with the nave 22 parallel with the rear plate 18 and the transe )t 123 extending at right angles thereto and within the enlarged portion 21 before mentioned. The nave portion extends for substantially the entire length of the bolt which is normally within the cusin v 10, and the transept portion extends for su )stantially the length of the le s of the H-sha )ed portion 21. The end of the bolt exten ing beyond the casing 10 is tapered as usual in look constructions, and near such tapered end but within the casing there are upwardly and downwardly extending projections 122 whose ends lie parallel with the ends of the H-shaped portion .21. On the upper face of the bolt 14. a groove 23 is out which extends through that portion of the bolt which lies within the casing and on the lower face a groove 21 is out which extends for the entire length of the bolt. The slots 23 and 24 with the remaining portions form the H-shaped portion, before mentioned. The transept portion 123 of the cross-sha ed slot intersects the slots 23 and 21 and, fin the purpose of making a continuous slot on the side of the bolt adjacent the rear plate 18, a plate 25 is inserted and held by means of screws 26, as seen in cross section in Figs.,11 and 12. In Fi 11 the plate 25'lies in the slot 24, while in *ig. 12, it lies in the slot 23, to meet the demands for locks on different doors. A spring 27, secured to 0. lug 28 on the rear plate 18, presses against the inner end of the olt 14 and forces it outward.

Near the upper end of the rear plate 18 there are two inwardly and horizontally extending plates 29 which are joined at right angles to vertical plates 30 which are spaced apart and lie opposite the coin slot 15 in the casing 11, before mentioned, and form a coin chute which leads downward to a mint adjacent the shaft 31 for the rear kno 13, as shown by dotted lines in Fig. 6. In normal position, the coin opening 15, the opening 32 in a slot closing plate 33, hereafter described, the coin chute 34, the slot 35 through the rear knob shaft 31, and the transept portion 23 through the bolt 14, are in line. There is also a slot through the plate 20, heretofore mentioned, which is in line with the coin chute 34. There is a second slot 36, imlicated by dotted lines in Fig. 6, to allow movement of an arm 37 on the front knob shaft sleeve 38. Said slot lies parallel with the rear plate 18.

The slot closing or indicating plate 33 is formed of a rectangular plate, as shown in Fig. 10, havin two vertically extending openings 32 w iich will register with the coin opening 15, and a horizontally extending openin 39 throih which extends the rear knob s iaft 31. n the rear side of the horizontal plate 33 there is a rearward projection -10 at the u )per end which is ada ted to rest upon the \orizontal plates 29 rom the rear plate 18 and thus support the slot closing plate 33, see Fig. 15. There are also rearwardly extending lugs 41 secured near the lateral edges of the plate 33 which are adapted to engage the sto )s 42 on the rear plate 18 and limit the site movement of the plate 33. At the lower end of said plate 33 and on the rear side also, a plate is secured which has .a central slotted portion 44 with a downwardly and inwardly inclined ortion 45 on either side and with the on s 46 turned at right angles to the plate 33 to form lugs which will be engaged by the coin, as hereafter described. Said plate lies within the slot in the bolt 14 which is adjacent the casing 10. As shown in Fig. 11, these lugs 46 project within the slot 23, while in Fig. 12, said lugs project within the slot 24. In the normal position of the lock with the bolt thrown,'one of the slots 32 mates with the coin opening 15 and with the coin chute 34 and the inclined portion 45 lies 0 posite the transept portion 123 through the liolt 14.

The front knob shaft is formed of two parts, an inner core 47 which has one bearmg in the rear plate 18 and the other in the front knob 12 and an outer or sleeve portion 38 which has the projecting arm 37, before mentioned. That portion of the inner core 47 which lies within the casing is circular in cross section and has a longitudinal slot 48 central therewith. A pin 49 is inserted into the end of the cylindrical portion which lies adjacent the casing 10 and fits within a slot 50 in the sleeve member 38, whereby said sleeve member is turned when the inner core member 47 is turned by the action of the knob 12.

The portion of the sleeve portion 38 which lies within the casing is substantially cylindrical and is annular in cross section and has slots 51 which mate with the slot 48 in the core 47. The arm 37 is secured to said cylindrical sleeve member 38, substantially midway between the front and rear casings, said arm extending through the slot 36 in the plate 20 and normally lies within the nave portion 22 of the cross-shaped slot within the bolt 14, as shown by dotted lines in Figs. 6, 7 and 8. A short link 52 is attached to said arm 37 near the sleeve and its outer end is caught by a flat spring 53 which is secured to the transverse plate 20 by a bolt 54 and serves to return the front knob shaft members 38 and 47 to their normal position, as shown in Fig. (i. There is a slot 50 on each end of said sleeve 38.

As shown in Fig. 4, the inner end of the front knob 12 is threaded and an internally threaded sleeve which has one flange 56 is screwed onto the threaded end of the knob 12 so that said (lunged end 50 bears against the inner side of the casing 11.

bus after the core 47 of the knob shaft is inserted into the central slot 57 of the knob 12, it is impossible to remove said knob from the outside.

The inner knob shaft 31 has a bearing in the rearwardlyextending sleeve 58 from the rear plate 18 and that portion which lies within the casing is circular in cross section and has the central slot 3:"). which in normal position, lies opposite the (oin chute 34. A bar 59 is secured to one side of said knob shaft and lies against the rear plate 18 and the lower end thereof projects behind the bolt. 14 in the slot formed by the lug 122, the rear plate and the enlarged end portion 21 of the bolt. The end of the knob shaft adjacent the front. casing is formed to receive a porters key, which may be inserted through an opening ()0 in a boss (11 in the front casing 10. \Vhen the key is so inserted, and turned, it will cause the lower end of the bar 59 to bear against the inner end 21 of the bolt and against the plate 2:) secured therein and move the bolt inwardly against the action of the swing 27 to the position shown in Fig. 8. The outer end of the rear knob shaft has the rear knob 13 secured thereon by a construction very similar to that used for the front knob shaft 12.

For the purpose of adjustin the look so that it may be used on a different door from that for which the lock shown in Fig. 6, was intended, the casing 11 is removed, after which the inner parts of the lock are removed. The rear knob shaft is then inserted in the position shown in Fig. 10, with the bar 59 on the op osite side of the vertical plates 29 from wiat is shown in Fig. 6. The bolt 14 is then inserted so that the tapered outer end extends to the right and the spring 27 is secured to the left-hand lug 28 instead of to the righthand one, as shown in Fi G. The knob shaft sleeve 38 is removed from the core 47 and reversed so that the arm 37 will lie on the opposite side of the core 47 from the position shown in Fig. 6. The spring 53 is also moved from the left to the right hand side of the plate 20 and secured to the arm 37 by means of the link 52. The opening in the casing 11, through which the bolt 14 formerly extended, is now closed by means of a small plate 63 which lies on the outside of the casing, as shown by dotted lines in Fig. 13, and is secured by a spring 64 on the inside which bears against the walls of the casing and holds it securely.

With the parts of the lock in the positions, as shown in Fig. 6, where the bolt is thrown, a coin on being inserted through the coin opening 15, will pass through one of the coin slots 39. m the slot closing plate 33 into the coin chute 34 and fall downward and, passing throu h the central slot 35 in the rear knob shaft 31 will pass into the transept portion 123 of the cross-shaped slot in the bolt 14 and will be caught by the inclined ortion 45 on the plate 33. The front kno then being turned, the arm 37 on the sleeve 21$, will engage the coin within the bolt and cause the withdrawal of the bolt against the action of the spring 27 and the coin, pressing against the inwart projection 46 from the rear side of the slot closing plate 33, will move said slot closing date to the right from the position shown in Fig. 6 to that shown in Fig. 7, and close the passageway from the coin slot 15 to the coin chute 34. The bolt being withdrawn, the door may then be opened. Upon the release of the front knob, the sprin 53 will return the front knob shaft mem ers to their normal position, as shown its-Fig. 6, but the slot closing plate will remain in the position shown in Fig. 7, indicating to any one on the outside of the door that the booth is occupied. The occupant of the booth, upon leaving, by grasping the rear knob and turning the same, will move the rear knob shaft and associated parts to the position shown in l" i g. 8, where the lower end of the arm 59, is shown as having caused the withdrawal of the bolt 14 not the timer end of said arm has engaged one o the inward projections 41 on the slot closing plate 33 and pushed it to the left, again opening the passageway from the coin opening 15 through said plate 33 to the coin chute 34. Upon the releasing of the rear knob 13, the spring 27 will cause the bolt 14 to be thrown and such movement 'ill move the arm 59 on the rear knob shaft 31 to its normal position, as shown in Figs. (3 and 7.

\Vhile there are many minor changes which may be made upon this lock, wlnch will materially change its appearance, it is not thought that they will alter the nature of the invention and it is not desired to claim the exact features herein shown.

It will be noted that with this construction and method of securing a knob shaft, it is impossible to remove the knob shafts or to remove the lock itself from the door without unusual violence except by opening the front door.

In the drawings a counter has been shown as secured to the rear plate 18 and operated by a link from the slot closing plate 33, but this constitutes no important feature of the invention.
